Paragraph 0016-0017, (2017/05/04)
The invention relates to a synthetic method of cyclopropylpropionic acid. Technical problems of synthesis operation difficulty and expensive raw material are solved. A conventional industrial raw material cyclopropanecarboxaldehyde is used as a starting raw material and triethyl phosphonoacetate undergo a Wittig reaction to obtain 3-cyclopropyl-ethyl acrylate; 3-cyclopropyl-ethyl acrylate and sodium borohydride undergo reduction of double bonds in the presence of Lewis acid to obtain 3-cyclopropyl-ethyl propionate; and 3-cyclopropyl-ethyl propionate is hydrolyzed under an alkaline condition so as to obtain cyclopropylpropionic acid. A chemical equation is as shown in the specification.
